Title: Help!!popping out the exhaust
Post by: Hobeau on March 02, 2009, 07:20:31 PM
Hey all,
This is a new build....76 ironhead   S&S stroker 74 inch Hi-4 ignition  S&S super E   all new. First start kicked it over 3 times without key 
on, turned on key,  fired right up. Ran it for one minute...shut off.
Let it cool off, kicked it 1 time without key .key on  started first kick......  If I try to roll on the throttle  it pops out the pipes  Suggestions and advice are greatly appreciated

The popping out the pipe on my evo turned out to be a cut intake manifold seal.  It showed up with WD-40.

I'd check advance first.  what about jetting, if too big... you may be over carburetored
